TMZ has learned 51-year-old Mark Hardy is in police custody after his daughter told cops that Mark "put his hand down [her] shorts and touched her genital area without her permission."
Hardy was arrested at the legendary Mayflower Hotel in D.C. -- where the alleged incident was said to have occurred early this morning. He's set to face a judge later today on the charge of misdemeanor sexual abuse.
UPDATE: TMZ has just received a statement from L.A. Kings saying simply, "We are aware of the charge. Due to the legal nature of this matter, we will not have any additional comments at this time."
